I haven't even noticed, when this blue-green algae first appeared in my freshwater tank. And not it is impossible to get rid of it. I've already read some info on the topic, like https://www.thesprucepets.com/cyanobacteria-blue-green-algae-1378628 or https://thepets.net/how-to-get-rid-of-blue-green-algae-in-a-freshwater-aquarium/ but want to ask for real experinece to prevent killing beneficial becteria. Any thoughts?
